Power Management gauge disappeared

Hi. I had a problem with Power Management bug (described here http://chris.brandlehner.at/Brandlehner/cab_blog.nsf/d6plinks/CBRR-6YWBNV) and solution to restore default policies worked fine for me. The problem is I cant see power gauge in the taskbar (so I cant control easily how much time I have left when on battery and so on). It might not be the big problem but wonder how to fix it. I would appreciate your help. Regards, Oliwier
